What it is
The Vaillant 0020127227 is a temperature sensor, designated TE, TS and TO, used across the Vaillant geoTHERM VWL air-to-water heat pump range. It measures system temperature at its fitted position and passes that reading to the appliance's control electronics. It is a service part for the 230V VWL models listed below.
Signs this part needs replacing
- Temperature readings that disagree with a calibrated thermometer taken at the same point on the circuit
- The heat pump short-cycling, or failing to reach its set flow temperature
- Fault codes or lockouts relating to temperature sensing
- Erratic or implausible temperature values shown on the appliance display
- Defrost cycles running at the wrong time or not initiating at all
Before you order
- Confirm the model number on the appliance data badge matches one of the fitments listed above
- Check the sensor designation (TE, TS, TO) against the position you are replacing
- Inspect the sensor lead and plug for mechanical damage or corrosion before condemning the sensor itself
